Abstract
The invention provides a low-field nuclear magnetic resonance system for measuring a magnetic resonance signal of an object. The low-field nuclear magnetic resonance system includes a pre-magnetization module, a uniform magnetic field coil module, a pulse and receiving coil module, a filter amplifier module, a signal acquisition module and a processing module. The pre-magnetization module is used to establish a pre-magnetization field in the object to increase magnetization of the object. The uniform magnetic field coil module is used to change a resonance frequency and background magnetic field intensity of the object during nuclear magnetic resonance measurement by regulating a magnetic field of the coil. The processing module further includes a programming object for controlling timing processing and signal analysis of the measurement process.
